ICD-10 Code J95.811 – Postprocedural pneumothorax (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J95.811 – Postprocedural pneumothorax
What it is
J95.811 identifies a pneumothorax that occurs as a complication after a procedure. It means air has entered the pleural space following an intervention, causing partial or complete lung collapse.
Clinical signs
Clinical features vary; refer to documentation. Common findings include sudden chest pain, shortness of breath, decreased breath sounds, and imaging evidence of air in the pleural cavity after a procedure.
When to use this code
Use this code when the record clearly links the pneumothorax to a recent procedure, such as a biopsy, line placement, thoracentesis, or surgery. Code it only when the provider documents the condition as postprocedural or procedure-related. If the chart does not clearly establish the relationship, check documentation.
Do not use for
Do not use this code for spontaneous pneumothorax, traumatic pneumothorax, or a pre-existing pneumothorax present before the procedure. If the cause is unclear, do not assume it is postprocedural.
Coding tip
Look for explicit provider documentation tying the pneumothorax to the procedure before assigning J95.811.
